This invention relates to new and useful improvements in typewriting machines generally, although more particularly to a column stop mechanism therefor, and constitutes a division of our co-pending application Serial No. 581,702, led Dec. 17, 1931. y

Among the several objects of our invention are to provide a typewriting machine with a series of column stops which are arranged at the rear of the machine; to mount said column stops on a supporting frame for swinging movements in a direction fore and aft of the machine; and to automatically and frictionally retain each co1- umn stop in either its active or inactive position.

The invention is `illustrated as applied to the y Well known Royal machine `but many of the features thereof are applicable to other typewriters. The machine includes the usual main frame 1 which supports theA usual track upon which runs a carriage 3 having endfplates {1 -@Which support a platen 5. An escapement rackrbar 6 is pivotally" supported on the carriageand is normally drawn provided with upper and'lower angular recesses 13 and 14 to receive correspondingly shaped extensions on the ends of the rackbars and there-1v by prevent turning of the bars relative to each other and relative to the plates. Upper and lower clamping screws 15, -16 serve to'clamp eachj plate l2 against the upperr andlower bars. Rigidly connected with each end plate 12 is an outwardly projecting threaded stud 17 having a flat upper surface 17a which ts into aV correspondingly shaped opening 17b in the adjacent end plate 4 of the carriage. Clampingnuts*18,- 18 y are mounted on the threaded 17 and are clamped against the opposite'faces vofA the end wall 4fof the carriage. The upper and lower stop bars 10 and `1l are rectangular in cross section. The lower face of the upper 'bar ll() vis. formed with a series of transversely extending grooves v19 and the upper face of the lower'barj'll is formed with a series of transversely (disposed, grooves 20, 'the grooves 19, 20 being arrangedinpairs andlsplaced apart at distances corresponding vto letter space intervals. Supported Onjithe 4stop;frame` al isja series of columnr stops` B,1there"beingfonefoithese stops for each pair'of upperandglowerA grooves 19 andv20. kIn other'liwords; ithesefstopsflfare mounted on the `rstopframe` Afatslettergspace;

necting portion 25. Each stop B is positioned on the frame A so that the arms 21, 22 are disposed ,on opposite sides of the upper rack bar andy the legs 23, 24 are disposed on opposite sides of the lower` rack bar 11, the cross bar or bridge 25 extending between the bars 10 'and 11 and into the upper and lower transverse grooves 19 and 20. The upper ends of the arms 21, 22 are rounded and the distance between theseends is substantially equal to the width of the rack bar 10 s`o as to permit the stop to swing from an inactive forward position to an active rearward position or vice versa, the rounded ends ofthe arms constituting pivots or fulcra for the stop'. The lower ends of the legs 23,. 24 are spaced apart a distance considerably greater than the width of the lower rack bar 11 so as to permit the stop being swung from one extreme position to the other, the legs cooperating with the lower rack bar 11 to limit the swinging movement of the stop. The height of the cross bar or bridge 25 of the stop is less than the distance between the top wall of the groove 19 and the bottom wall of the groove 20. The lower edge of the bridge portion 25 adjacent the rear leg 24 is provided with a flat 26 which rests on the bottom wall of the groove 20 when the stop B is in its inactive or inoperativeposition, 'as shown in Figure 4. The lower edge of the bridge portion 25 between the forward leg 23 and the at 26 is formed with a recess 27 to form a clearance and thereby permit the free rearward swinging of the stop B to the position shown in Figure 8. It is desirable to frictionally retain each stop B in each of its extreme positions. rTo this end, each' stop B is provided with a spring 28 which is in the form of a spring wire bent between its ends to form upper and lower spring arms 29 and 30 respectively, the bend of the spring engaging a headed stud 31 which is attached to the stop. The arms 29, 30 extend forwardly between the upper and lower krack bars 10 and 11, and the free end of the lower arm 30'is provided with an offset 32 which is located in a seat 33 formed in the front edge of the stop. The free end of the upper arm 29 00' is curved upwardly and downwardly to form a cam which has sliding engagement with the lower face of the rack bar 10 when the stop B is in its active position as shown in Figure 8 and with the lower front corner of the upper rack bar 10 when the stop B is in its inactive position as shown in Figure 4. Thus when the stop B is in its active position as shown in Figure 8, the lower angled edge of the bridge 25 between the front leg 23 and the at 26 is seated against the rear upper corner of the wall of the transverse groove 20 and is frictionally held thereagainst by the tension of the spring 28 due to the' arm 29 thereof bearingagainst the under face of the upper rack bar 10. When the stop B isl moved to its inactive position, as shown in Figure 4, the free end of the upper arm 29 of the spring 28 will snap over the lower front corner of the upper rack bar 1,0 and the flat\26 will be yieldably retained in contact-with the lower wall of the groove 20. It will, therefore, be seen that the stop B is capable of being rocked rearwardly to an active position or forwardly to an inactive position and that yieldable means are employed for automatically and frictionally retaining the stop in either of its extreme positions.

the lower rack bar 11.

In order to retain the center portions of the upper and lower rack bars 10 and 11 against relative movement, we have provided a tie plate 34 which is formed with upper and lower angular openings 35 and 36 respectively for receiving "the upper and lower rack bars 10 and 11, as shown in Figures 6 and 7. The'upper faces of the upper and lower rack bars 10 and 11 are respectively formed with transverse recesses 37, 38 for respectively receiving the upper walls of the openings 35I and 36. The lower end of the plate 34 extends downwardly below the opening 36 and terminates in an arm 39 which underlies A filler block 40 is disposedV between the arm 39 and the lower face of the rack bar 11 and a clamping screw 41 passes through the arm 39 and`the block 40 and is threadedly engaged in the lower rack bar 1.1, thereby securely retaining therack bars 10, 11 and the tie plate 34 against relative movement.

A plurality of key-selected denominational stop levers E are pivotally mounted on the rear of the machine frame for cooperation with the column stops `B in the usual manner." A keyoperated setting nger 59 is located in front of 100 the column stops B and when the nger is moved rearwardly it will engage and swing the registering column stop B to its active or operating position.

Our invention also includes a stop restoring This stop restoring device G is mounted on the v main frame 1 of the machine at a point in rear of thestops B. This device includes a U-shaped frame 122 including a top 123 havingdepending legs 124, 125 which are pivoted by a stud 126 and a pivot screw 127 to forwardly extending 115 arms 128, 128 of a bracket 129 which is secured tothe supporting bracket 61 by screws 130, as shown particularly in Figures 1 and 3. The axes of the pivots 126, 127 are in alinement and in a plane extending parallel with the rack bars 10 and 11 so as to permit the restoring device G to be swung toward and away from the column stops B. The top 123 projects forwardly beyond the supporting legs and the forward edge of said top is formed into a cammingsurface having a high point 131 located centrally between the attaching legs 124, 125. Two rollers 132, 133 are journaled on vertical axes 134, 135 carried by the top 123. Theserollers are disposed on opposite sides of the high point 131 of the camming 130 edge of said top, the camming edge projecting forwardly beyond said roller as clearly shown in Figure 3. In other words, the high point 1-31 of the camming edge is intermediate the rollers 132, 133, and said rollers project forwardly be- 135 yond the camming edge at opposite ends thereof. The rollers 132, 133 function to move easily the column stops B in their first or initial movement over the high point X of the cam surfaces on the cross bars 25 of said stops. The leg 124 projects 140 downwardly below the pivot stud 126 to form a stop arm 136 which is adapted to engage a xed stop 137 xed to the arm 128 of the attaching bracket 129 to limit the rearward swinging movement of the device as shown particularly in Fig- 145 ure 8. A coil spring 138 has its upper end engaged with an ear 139 attached to the frame 122 and its other end engaged in an. ear 140 secured to the attaching bracket 129. This spring'138 functions to normally retain the restoring de- 1() 136"bearing against the stop 137 as shown in Y Figure 8. The arm 125 of the `frame 122 extends below the pivot screws 127 and terminates in a stop arm 141 which is adapted, when the restoring device G is swung forwardly to operative position, to engage the bracket 129 and thereby limit the forward movement of the device. In order to assist in moving the device to its operative position, we have provided an upwardly extending nngerpiece` 142 whichlis at tached to vthe top 123 of the pivot frame 122. Thus when it is desired to restore the column stops B to their normal or inactive positions, the operator engagesl the fingerpiece 142 andswings the restoring device G forwardly so as to cause the stops B to rst engage one or the other of the rollers 132, 133, depending on the direction of movement of the carriage, and then to engage the high point 131 of the cam edge of the top- 123, the parts beingv so arranged that the high point 131 of the cam will completely restore the column stops B to their normal positions.

From the foregoing, it will be observed that we have provided a typewriting machine with a series of column stops which are arranged at the rear of the machine; that said column stops are mounted on a supporting frame for swinging movements in a direction fore and aft of the machine; that each column stop is automatically and frictionally retained in either its active or inactive position;. and that a normally inoperativev stop restoring device is adapted to be manually moved forwardly into position to be engaged by the lcolumn stops during movement of the carriage in either direction to thereby restore all of the column stops to their normal or inactive positions.
